VALVE MECHANISM FOR BASIN-OUTLETS.

SPECIFICATION forming part of Letters Patent No. 767,450, da A g 16,1904.

Application filed February 16, 1903. Serial No. 143,574. (No model.)

To all whom, it may concern:

Be it known that I, Gusrrvn A. SODERLUND, of Somerville, in the countyof Middlesex and State of Massachusetts, have invented certain new anduseful Improvements in Valve Mechanism for Basin-Outlets, of which thefollowing is a specification.

This invention relates to means for controlling the outlet-valve ofhand-basins and similar receptacles, and relates particularly to meansfor controlling that type of outlet-valve which comprises areciprocating valve at the center of the bottom of the basin, althoughthe invention may be applied to other forms or locations of valves.

The object of the invention is to provide an economical andeasily-operated mechanism for the purpose stated, the parts of whichmechanism may be easily assembled.

To these ends the invention consists in the construction and arrangementof parts substantially as hereinafter described and claimed.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation, partly in section, of the parts ofa mechanism embodying my invention applied to the outlet-valve of anordinary hand basin or bowl. Fig. 2 represents a section on line 2 2 ofFig. 1. Fig. 3 represents a detail section on line 3 3 of Fig. 1. Fig. 4is a view similar to Fig. 3, but showing the parts in different relativepositions. Fig. 5 represents a view similar to a portion of Fig. 1,showing a different embodiment of my invention.

The same reference characters indicate the same parts in all thefigures.

The embodiment of my invention shown in Figs. 1 and 2 will be firstdescribed. An ordinary bowl is represented at 10, the top of the basinor washstand being indicated at 11. 12 represents avalve for controllingthe outlet from the bowl, the said outlet communicating through a casing13 with the discharge-pipe 14. Preferably cast integral with the innerwalls of the casing 13 are pocket-lugs 15, diametrically opposite eachother, said lugs being adapted to receive the ends of the shaft or studs17 of a cam 16. The pockets or recesses in the lugs are open at the top,so that the cam and its shaft or studs may be readily dropped thereintowhen the parts are being assembled.

The valve is shown as provided with an ordinary stem 19, the latterhaving a foot-piece 18 adjustably connected with its lower end, saidfoot-piece being adapted to bear upon the cam, so that when the latteris moved between the positions shown by full and dotted lines in Fig. 1the valve will be raised and lowered through the medium of thefoot-piece and stem. By adjusting the foot-piece 18 the amount of theopening of the valve maybe adjusted. For instance, the amount of openingmay be reduced by'setting up the foot-piece to such an extent that whenthe valve 12 is seated said foot-piece will not bear upon the cam.Projecting downwardly from the shaft of the cam is an arm 20, said armextending through an aperture 21 formed in the inner end of a rod 22,the latter being adapted to reciprocate in a bearing, preferably packed,formed in the side of the casing 13. The aperture 21 is contracted atthe center, and flares in opposite directions therefrom, so as to allowlittle or no lost motion between the rod 22 and the cam, althoughpermitting the arm of the cam to assume different angles relatively tothe rod. The rod 22 is adjustable in length, as by forming it in twosections, one having a sleeve portion fitting over the end of the otherportion, and the two being secured together by a suitable screw. Theouter end of the rod 22 is provided with a block or head 23, having alongitudinal slot 24 and a lateral slot 25.

An operating-shaft is shown at 26, said shaft extending up through thetop of the basin and having an operating knob or handle 27, whereby saidshaft 26 may be partially rotated. The lower end of the shaft 26 extendsthrough the longitudinal slot 24 of the block 23, and said shaft isprovided with an arm 28, having a downwardly-projecting pin 29 passinginto the lateral slot 25 of the block 23. Suitable means, such as aholding nut or plate 30, secured to the extreme lower end of the shaft26, serves to prevent the separation of the parts when connected at thispoint. The shaft or rod 26 is also preferably adjustable in length, sothat its lower end where connected with the outer end of the adjustablerod 22 may be brought into accurate alinement with the horizontalbearing formed in the side of the casing 13 for the rod 22. This enablesthe parts to be applied to the bowl in such a manner that there will beample freedom of action for the rod 22.

It will now be readily understood that by means of the knob or handle 27the shaft 26 may be rotated so as to carry the arm 28 from the positionshown in Fig. 3 to that shown in Fig. i, or vice versa. During suchmovement the head 23 is guided on the shaft 26 by means of the slot 24,while the pin 29, passing through the lateral slot 25, acts toreciprocate the head 23 and the rod 22 and oscillates the cam from theposition shown in full lines in Fig. 1 to the position shown by dottedlines in said figure, or vice versa. It will be readily understood thata very slight movement of the knob 27 will suffice to open the valve toits full extent, said movement of the knob 27 being ninety degrees orless.

I have found in practice that the bearing afforded by the top 11 of thebasin is sul'licient to prevent any such lateral movement or deflectionof the lower end of the shaft 26 as would interfere with the properoperation of the cam 16, since the connection of the parts is such thatthe friction is but very slight. I may, however, in some cases apply aguidebearing 31 for the lower portion of the shaft 26, such as indicatedby dotted lines in Fig. 1.

It will be observed' that all the parts may be readily assembled, therebeing no screwiittings either at the point of connection between theshaft 2b and the rod 22 or between the shaft 22 and the cam. Theopening-andclosing movement of the valve is much more rapid than can beobtained where such movement is dependent upon the working of a screw.Moreover, the operation of the parts is much smoother and less liable toget out of order than is the case where gears are employed to convertmotion from one shaft to another, since the teeth of said gearsareliable to catch or stick.

In Fig. 5 I show a different embodiment of a part of my invention, inwhich the cam instead of being separate from the foot-piece 18, is asubstantially conical projection 180 on the lower side of or below thefoot-piece, said projection or cain bearing on the end of the rod 22.Said end is preferably conical or tapering and is in sliding contactwith the cam 180. W' hen the rod is in the position shown in full linesin Fig. 5, it permits the valve to rest by gravitation on its seat, and

when the rod is moved to the position shown in dotted lines it raisesthe cam and valve.

The construction last described constitutes a part of the preferredembodiment of my invention on account of its simplicity and relativechcapness.

Owing to the fact that the rod 22 and shaft 26 are adjustablein length,the device is rendered simple in operation and. easy of application tothe particular location where it is desired for use. As has been stated,the adjustability of the shaft or rod 26, which in the embodiment of theinvention shown in Fig. 1 may be by providing for vertical adjustment ofthe handle 27 upon the shaft 26. enables the rod 26 to be brought intoalinement with its bearing, so that there will be no binding, and thelongitudinal adjustability of the rod 22 enables it to be so fitted thatthe cam may be operated just far enough to hold the valve in elevatedposition when the handle 27 is released. As indicated by the dottedlines in Fig. 5, the rod 22 is designed to be advanced far enough sothat the point of the conical projection 180 may rest upon the top ofthe rod, in which position the parts may be left as long as desired. Itis to be understood. that with the embodiment of the inventionrepresented in Fig. 5 the adjustable rods 22 and 26 and theirconnections will be substantially the same as in the other form shown.In Fig. 1 the position of the cam 16 (indicated by dotted lines) issupposed to be such as will support the valve in elevated position evenwhen the operator releases the handle 27.

I claim- A device of the character specified, comprising anoutlet-valve, a cam for actuating the valve, a rod adjustable in lengthand extending through the valve-casing and operatively engaged with thecam, the outer end of said rod having a head provided with alongitudinal slot and a lateral slot, and a shaft substantially at aright angle to the rod and having an arm provided with a pin extendingthrough the lateral slot of the head of the rod, a portion of the shaftwhich is in alinement with its longitudinal axis extending through thelongitudinal slot of the head of the rod for guiding the latter, meansbeing provided for rotating the shaft to cause the pin carried therebyto reciprocate the rod through the medium of the said lateral slot.

In testimony whereof I have affixed my signature in presence of twowitnesses.
